Imagine what would happen if a neighborhood a few blocks away from yours started getting hit by a string of burglaries. Would you just sit by and wait to be the next victim? I doubt it. You and your neighbors would probably start looking through police reports and listening to… Read More

Think about the last time you cleaned out your garage or closet. If you’re anything like me, you probably discovered things you never remembered buying, plus an item or two that you thought you’d gotten rid of a long time ago. The same is probably true of your network. The… Read More

A couple years ago, we did a series of blogs on common network security misconceptions in local government. Since a lot of that information is still relevant today, we thought we’d go back through as a refresher course. First, let’s talk about “public” information. Just because some of the data… Read More

In a year chock full of juicy network security headlines, two of the biggest so far have been WannaCry and the Equifax breach. Here’s a quick refresher: WannaCry broke out in May (fizzling shortly thereafter), taking advantage of a known vulnerability in the SMB protocol and utilizing an… Read More

Since 2012 (before Threat Intelligence was cool) we’ve published a public list of malicious IP addresses for the community. It goes by many names: CINS Army, CI Army, CINS … In any case, over 10,000 users (these days those ‘users’ are automated tools, scripts, and open source projects)… Read More

With news breaking on the use of an Apache Struts vulnerability in the recent Equifax breach, we thought we’d shed some light on Struts exploits from our perspective.

Virtual Touchscreen with Support wording You will probably find this question at the end of a blog, on an online “submit” form, on a customer ticket, or any other service-related web page you use daily. “How likely are you to recommend THIS WHATEVER to your friends and colleagues?” Then, you… Read More

One of the most confusing aspects of malware is that infiltrators never devised a better method of getting their software onto networks. Up to this point, ransomware and malware developers have relied on phishing emails and watering holes (targeted, compromised web sites hosting malicious code) as delivery methods;… Read More

Today, in the final installment of our Security Spring Clean series, we encourage you to be bold. We are going to guess, and we think we will be right, that somewhere in the back corner of your server room there’s a box that has been plugged into the switch since… Read More

Having the right hardware is important. Software too. And you know how we feel about the importance of training your people. But the heart of any business is its data. For some businesses, it helps them get products to market faster. For other businesses, the data is the product. Read More

The weakest part of any network isn’t some tool in the data center or some device on the wire. No, it’s the people who are logging in. We’ve said it repeatedly here, and as long as people keep providing us with examples to cite then we’ll keep saying it over… Read More

If science does anything for you then you’ve no doubt heard of the large hadron collider. It’s the particle accelerator operated by CERN, the European agency focused on nuclear research. The organization recently decided that it was time for large-scale improvements to its most powerful piece of equipment. Read More

Traditionally, network security has been reactionary. Protection didn’t often happen until after infection. But in the early days that was OK. Compared to now, networks weren’t complicated. Finding and removing malicious software was relatively easy. Today, however, networks are more complicated and the abilities of hackers to get inside are… Read More

Security headlines over the last week or so have been talking about Russian police raids at the end of November that may have put an end to the Dyre malware variant. The ring of cybercriminals taken down in those raids was almost the exclusive users of Dyre — malware that… Read More

Network security can’t be a passive thing. Those who want into your network are constantly figuring out new ways to get there. If you’ve read this blog for any length of time, that should be a somewhat familiar message. And if that message feels familiar, so should this one. Read More

The annual list of bad passwords was released last week. The list for 2015 looks a lot like the list for the previous years. Still, these are always good for a bewildered chuckle. Password is still an unfortunately popular password. So is 123456 and the longer 12345678. Sequential key combinations… Read More

There was a lot of talk last week about Microsoft putting its browser Internet Explorer out to pasture. If you missed the news — hard to do for anyone with even a passing interest in technology, but not impossible — the software giant announced that it was no longer… Read More

Over the last few weeks, we’ve been looking at common security misconceptions that plague state and local governments. There’s one more that we’ll examine on the blog although we identify six in the ebook we recently published. This last one is different than the three that have come… Read More

There’s nothing new about social engineering. It’s old-fashioned con artistry with a fancier sounding name. The Trojans had their horse. The schemer on the streets has his game of three-card Monte. And hackers and cybercriminals have their own tactics. You’ve no doubt heard of (and received) phishing emails, when… Read More

Here’s a pretty staggering number: 34,220,504. That’s the number of personal records exposed, according to the Identity Theft Resource Center, through November 2015 because of government data breaches. While that number does include some pretty high profile federal breaches, it also includes many more at the local level that… Read More

The Tarrant County Courthouse located in Fort Worth, Texas. NRHP Ref 70000762. There’s a saying that we’ve always liked: It’s a poor artist who blames his tools. There are other versions of that.

We are going to admit right from the outset that this post will seem self-serving. We are a company that provides a managed security service, so when we say what we are going to say you’ll think to yourself, “Well, sure. Of course that’s your opinion.” But, we’re going… Read More

A dive in to our CINS data revealed some telling numbers with regard to network security in state and local government agencies, including education – the so-called SLED organizations. The bottom line? The vast majority of critical malware-related alerts we see on our Sentinels come from the Government… Read More

We’ve all seen them, whether we are at work or at home, those update boxes that pop up and tell us that there’s a new version of some piece of software that we probably didn’t know we had or didn’t think was important. We’ve all probably had the same reaction:… Read More

An interesting study just released by the Pell Center for International Relations and Public Policy at Salve Regina University on the state of cybersecurity readiness in state governments confirmed what our own data has been showing us.

It’s only natural for the growth of certain technologies to slow as they become more and more commonplace. That’s why the headlines talking about the slowing growth of the tablet or smart phone market are always a little surprising. Of course the growth of those markets is going to slow… Read More

Unless you make it a habit of reading blogs about bitcoin or spend your spare time on sites dedicated to network security then you may have missed the announcement last week by the FBI on ransomware. OK, to be fair, it wasn’t an official announcement, just a comment from… Read More

Are we witnessing the death of malware? According to this story at InfoWorld the answer seems to be … maybe. While it will likely never go away completely, it’s less and less becoming the tool of choice for many hackers. It seems, according to several studies quoted… Read More

The recently announced hack of the web-based version of the WhatsApp messaging service didn’t draw a lot of attention. Why should it? The number of people affected was relatively small in comparison to other recent hacks — just (just?!) 200,000 users. Another reason that this hack went relatively unnoticed was… Read More

In today’s world, the landscape of network security is constantly evolving. High profile security breaches and vulnerabilities (think Ashley Madison, Target, and Heartbleed) have prompted increased awareness of cybersecurity, spurring on the continued advancement of emerging technologies. But even the creation of updated devices and highly technical tools hasn’t… Read More

It’s a question we get regularly. “Do you guys protect against DDoS?” The question makes sense. Distributed Denial of Service attacks should be top of mind for business owners and network security professionals. The data bears that out. Consider these statistics from a recent study on the state… Read More

Quick disclaimer: We won’t be talking about specific security tools in this post, because, as you will see, layered security isn’t about specific tools. It’s about building visibility into your network, and since your network is unique the tools that makes sense for you might not make sense for… Read More

The limit to what modern technology can do seems to have no ceiling, but neither does the intricacy and methods by which your secure data can be breached. Any organization hoping to protect its information employs security measures not only through its hardware and software, but also through the team… Read More

For small businesses wanting to get serious about security, there are two attitudes that need to change. ‘I’m too small to hack.’ The first is that your business doesn’t have information worth stealing. It’s not true. It’s important to recognize that even as a small business you have information that’s… Read More

You’re to be forgiven if where you’ve placed a lot of your network defenses is on your system’s spam filter. After all, until as recently as 2010, 90 percent of all email messages sent qualified as spam. That’s not true anymore. According to security firm Symantec, the number… Read More

When you call your business Hacking Team, a few chuckles when you are the victim of a hack are understandable. Unfortunately, so are the pained expressions when people find out why you got breached. News went from bad to worse in early July for the Italian company Hacking Team after… Read More

In an IT world where budgets are shrinking but responsibilities are growing, it’s becoming far too commonplace to see teams of only one or two people attempt to manage technology for an entire organization. Not only are they trying to manage a data center, they are also tasked with managing… Read More

It seems like we hear stories on yet another security breach every day. OPM is the biggest one lately, and there might even be another ‘big’ breach by the time I’m finished writing this post. One of my favorites recently was the Astros ‘hack’. The St. Louis Cardinals had… Read More

The Office of Personnel Management. It has a predictably boring name for a government office. Essentially, the Office of Personnel Management is human resources for the government’s civil service employees. When it comes to hackers and government offices, this might seem like low hanging fruit. In reality, it’s just the… Read More

Third-party contractors and vendors are increasingly necessary for doing business, but are typically the weakest links in the cyber security chain. Just look at the headlines. A compromised contractor login is believed to be behind a pair of recent breaches at the U.S. Office of Personnel Management. The first… Read More
